Filed Apr. 12, 1962, Ser. No. 187,066 11 Claims. (Cl. 297-440) This invention relates to a new and improved furniture Construction.

The upholstering of furniture such as chairs and sofas or the like has long been the work of skilled, experienced craftsmen. The usual construction for such chairs and other furniture is the making of a wooden frame, applying stuffing and springmaterial to the frame and thereafter applying upholstery or covering fabric materials to the outside surfaces of the completed chair or other furniture piece. Getting the fabric to stretch tightly across all of the irregular surfaces of the furniture piece which usually includes a back, arms and seat portions is most difiicult and requires much practice and training to accomplish with any degree of dexterity. Thus the cost of unholstered and overstuffed furniture is extremely high. The present invention is concerned generally with the preupholstering of parts of furniture pieces which may thereafter be assembled into a complete furniture piece, such as a chair, with all of the upholstering completed upon assembly.

A principal object of the present invention is to provide a furniture construction in which various parts of the furniture piece may be preupholstered and later assembled into a completed piece of furniture.

An important object of this invention is the provision of preupholstered back and arms, preupholstered seats and including removably fastenable legs to act as interr locking means between the preupholstered seat and preupholstered back and arms for completing an assembled piece of furniture.

An important object'of this invention is to supply furniture components which may be easily upholstered and the upholstered components subsequently assembled as a complete furniture unit.

Still another important object of this invention is to provide furniture components which may be upholstered by open stapling and the upholstered components later assembled in such a manner that most of the open staples are concealed.

Another and still further important object of this invention is to equip a furniture unit with a seat portion having holes through locations adjacent the corners thereof, arm portions having holes in alignment with the holes in the seat portion, nut means associated with the holes in the arm portions, a back fastened to the arm portions, and leg members having threaded studs passing upwardly through the holes in the seat portion, through the holes in the arm portions and threadedly engaging the nut means associated therewith to thereby rigidly hold the furniture components together as a unit.

Still another important object of this invention is to provide a furniture construction in which there is provided arm members with slidably removable top portions to thereby permit replacement of the normally excessively wearable portions of the furniture unit.

Another important object of this invention is the provision of means for attaching furniture arms to a furniture back.

Another'and further important object of this invention is the provision of a furniture back section for an upholstered piece of furniture in which the frame support includes substantial depth and means are provided therein for fastening arms thereto and having side closure panels 3,170,729 Patented Feb. 23, 1965 at the side extremities thereof to thereby conceal the arm' fastening means within the back section.

Other and further important objects and advantages Will become apparent from the disclosures in the followchair with portions thereof removed to show interior con struction.

FIGURE 3 is a sectional view taken on the line 33 of FIGURE 1.

FIGURE 4 is an exploded view of the components of a chair preliminary to upholstering and assembly thereof.

As shown in the drawings: I

The reference numeral 10 indicates generally an upholstered chair. It should be understood the present invention is concerned with a furniture construction and this construction may be employedin a chair or sofa or other piece, which includes the several sections of a seat, back, arm and legs. In the present instance the seat portion of the chair 10 is shown at 11. The back is shown at 12, spaced apart arms are shown at 13 and 14 and finally legs 15, 16, 17 and 13 provide the means for engaging the floor and spacing the chair proper and its seat 11 above the floor.

The particular furniture construction shown herein is important because it facilitates the employment of unskilled labor in upholstering the furniture. Also it is important to the particular construction to enable a shipment of furniture in a knocked down state and permitting easy assembly at the site of use.

The exploded view of FIGURE 4 shows the chair preliminary to upholstering thereof. The seat 11 includes a boxlike central portion 19 and a solid bottom plate member 20. The bottom plate 20 projects laterally outwardly of the box 19 to form spaced apart longitudinally extending side flanges 21 and 22 on which arms to be' subsequently described may rest. Similarly the bottom plate 20 is provided with a rearwardly extending flange 23 for reception of a seat back as will later be described. The central box portion 19 is relatively deep and is provided with springs 24 across the top thereof. A cushion or padding material 25 is placed over the springs 24 and is held in position by an outer covering of an upholstery fabric. While the seat portion 11 is separated from all other parts of the chair it is upholstered as shown in FIG-- URE 2. The padding material 25 is laid over the entire top of the boxlikc central section 19 directly onto the springs 24. Thereafter the outer covering fabric 26 has one end stapled to the back side of the wall 27 of the rectangular box 19 and is then pulled over the top of thecushion material 25 and thence down over the forward wall 28 of the box 19. The other end of the-material is then stapled to the underside of the bottom plate 20 just inwardly of the front edge thereof. Further, the

sides of the fabric 26 are preferably stapled along the.

box sides 29 and 30. There is no reason to attempt to conceal these staples on the back and sides of the box product. This is true because only one side of the material covering has to have its staples concealed and this is done on the easy to get at bottom of the plate 20. The upholstering or covering of the seat section with fab- I ric is made easy by reason of its being entirely in the open and permitting direct use of a staple gun around all of the sides of the seat box 19 excepting on the front whereas previously stated it is necessary to bring the fabric down over the front and staple or otherwise fasten it to the bottom plate 20.

The seat section 11 includes a plurality of holes 31, 32, 33 and 34. These vertically disposed holes are located at spaced positions in the bottom plate 20 of the seat section 11. Further the holes are preferably located adjacent the perimeter of the plate 20. The'holes 31 and 34 are in general alignment on the side flange 22 and similarly the holes 32' and 33 are in general alignment on the laterally spaced apart longitudinally extending side fiange 21. Generally the holes are disposed at the corners or near the corners of the bottom plate 20 to thereupon provide locating means for leg supports to be subsequently described.

Another section of the chair or other furniture piece is the back as shown at 12 in FIGURE 1 and in the exploded view of FIGURE 4. The frame structure for the seat back 12 includes a base member 35' disposed generally horizontally. A vertically spaced apart and generally parallel member 36 forms the top of the seat back frame. The sides of the vertically spaced members 35 and 36 are joined by laterally spaced apart front post members 37 and 38. The rearward portions of the bottom and top plates 35 and 36 are joined by generally vertically disposed rear post members 39 and 49. It is preferred that the back section 12 be provided with springs 41 extending vertically between the bottom and top plate supports 35 and 36. A soft cushion material 42 is mounted over the springs 41 and in somewhat the same general manner as the seat 11 was upholstered so also is the back section 12 upholstered. It is preferred that the upholsterer tack or otherwise staple one end of the fabric along the underside of the back edge 43 of the bottom plate member 35. Thereafter the fabric which extends the full width of the back 12 is carried upwardly and pulled over the top plate 36 and thence down over the front of the back wall 12. After pulling the fabric tightly over the padding material 42 it is stapled to the bottom side of the front edge 44 of the bottom plate 35. Here again there is nothing on the back which is concealed and which might make it difficult to upholster. The top plate 36 of the back 12 is automatically free of upholstering staples inasmuch as the covering fabric 45 is attached at one end to the underside of the bottom plate 35 and continues up the back, over the top plate 36 and thence down the front side of the back for attachment again to the underside of the bottom plate 35. The fabric 45 has its lateral side edges fastened to the outer edges of the side posts 37, 38, 39 and 40. No attempt is made to cover the side openings between the front and rear posts 37 and 39 and 38 and 40. It is preferredthat the upholstering cushion material 42 be tapered downwardly at the sides of the back section 12 andthat it be substantially eliminated at the lower portions of the side members 37 and 38 so that arm sections to be subsequently described may be attached thereto. The post member 37 is equipped with vertically spaced apart, longitudinally extending holes 46 and 47. Similarly the post member. 38 is equipped with corresponding vertically spaced apart, longitudinally extending holes 48 and 49. Following upholstering of the back section 12 the upholstered arm sections are then attached thereto through the holes-46, 47, 48 and 49.

As best shown in FIGURE 4 the arm sections 13 and 14 have their supporting frames clearlyshown. The arm 13 includes a base plate or strip member 50 havinga vertically disposed forward post 51 and a rearwardly disposed vertical post 52. The top of the arm 13 includes a top plate member 53 which joins the posts 51 and 52 at its forward and rearward ends. posed generally parallel to the bottom plate 50. There The plate 53 is dis outwardly as shown at 61.

is thus formed a rectangularly shaped frame which may be readily upholstered and attached to the back section 12. The frame for the arm section 14 includes a base plate 54, front and rear vertical posts 55 and 55a, and an adjoining top plate member 56. The top 53 of the arm 13 is equipped with spaced apart rail members 57 and 58. The rails include a top portion 59 adapted to be tacked or otherwise fastened as shown at 60 to the top strip member 53 of the arm frame. A slightly downwardly offset portion of the rail 57 projects laterally It is this portion 61 which acts as a tongue or rail for engagement by a cooperating cap member 62 to cover the arm 13. The rail member 58 on the inside of the arm member 13' is provided with a laterally inwardly extending lip or flange member 63 corresponding to the outwardly extending flange 61 on the rail member 57. The arm cap member 62 is provided with a top plate member 64 and downwardly extending side members 65 and 66. Longitudinally extending grooves 67 and 68 are provided in the interior of the leg members 65 and 66 respectively and constitute the means for cooperating with the outwardly extending rail portions 63 and 61 of the members 58 and 57 respectively. The interengagement' of the arm frame and the cap is shown in FIGURE 3. It is quite evident that the cap member 62 may he slid fore and aft on the track members 61 and 63 by reason of their engagement with the opposing slots 67 and 68 in the cap member legs 65 and 66.

The frames of the arms 13 and 14 are covered with an upholstery fabric 69 as shown in FIGURE 3. The fabric is tacked or stapled at 70 on the top plate 53 of the frame and thence carried down over the outer side as shown at 71, around the bottom plate 50, up the inner side as shown at 7'2 and over the top plate 53 for stapling at 73.

Similarly the arm 14 is provided with oppositely disposed rails 74 and 75 for engagement by a cap member 76 and more particularly by the longitudinally extending grooves 77 and 78 on the inward faces of leg members 79 and 80 respectively of the cap member 76. The cap 76 is providedwith a top plate member 8-1 which joins the legs 79 and 80. I

As best shown in 'FIGURE 3 the cap member 62 and 76'are covered with a cushion materal 82 and then covered with an outer fabric of upholstery 33 to thereupon provide a completely upholstered arm cap. The fabric 83 is preferably stapled or tacked at 84 on the inner side of the leg member 66 whereupon it is pulled outwardly around the bottom of the leg 66 and thence up the side thereof and over the top of the cushion material lying on the top plate 64. The fabric is then drawn over the far side of the cap, down the side of the leg 65 and around the bottom thereof for stapling at 85 to the inner wall of the leg 65.

The vertical post 52 of the frame constituting the arm 13 is provided with vertically spaced apart longitudinally extending holes 86 and 87 which are substantially in alignment with the holes 48 and 49 respectively in the back section '12 of the furniture. It should also be noted that the bottom plate 50 of the frame for the arm 13 projects rearwardly as shown at 88. This extension 88 is provided witha hole 89 which is in general alignment with the hole 33 in the seat section plate 20. A hole 90 in the bottom plate 35 of the back section is also in alignment with the holes 33 and 89 to permit an attaching means to join the several elements together. A nut element 91 is fastened to the plate 35 by means of rivets or the like 92 directly over the hole '90. The bottom plate 54 of the frame constituting the arm 14 similarly projects rearwardly forming an extension 93. The extension 93 has a hole 94 therethrough in alignment with the hole 34 in the seat plate 20. The bottom plate 35 of the back section 12 is similarly provided with a hole 95located between the front and rear post members 37 and 39. Directly over the hole 95 there is provided nut means 96 having laterally extending flanges 97 which constitute a means for attachment to the plate 35 by means of rivets or the like 98.

Following the upholstering of the seat back 12 and the arms 13 and 14 they are assembled by placing the back section 12 on the rearward extensions 88 and 93 of the arm frames. The holes 88 and 90 are generally vertically aligned when the forward side of the post member 38 abuts the vertical post 52 of the frame. Similarly the holes 94 and 95 become generally vertically aligned when the post member 37 abuts the rearward face of the post 55a of the frame constituting the arm 14. While in this position the arm portion 13 is securely bolted to the back section :12 through the horizontally aligned openings 86 and 48 and '87 and 49. Similarly holes 99 and in the vertical post 55a of the arm 14 are aligned with the holes 46 and 47 in the 'post 37 of the back'section '12. The assembly of the arm 14 to the back section 12 is shown in greater detail in FIGURE -2. A fastening bolt 101 passes through the horizontally aligned openings 47 and 100 and similarly a fastening bolt 102 passes through the aligned openings 46 and 99. The fastening is accomplished by a manual reaching into the back section 12 through the sides thereof between the forward post 37 and the rearward post 39. This facilitates easy engagement of the bolt members 101 and 102 by suitable wrenches or the like to draw the bolts up tightly for securely holding the back section fixedly with respect to the two spaced apart arm sections 13 and 14. The fastening of the arm section 13 to the back section 12 in a spaced apart position from the arm section 14 is similarly accomplished by bolt members not further shown-in detail because of their identity to the bolts used in the attachment of the arm section 14. I

It is in this condition that the furniture sections are placed together for final assembly. The back with its now integral arms are placed on the laterally extending side flanges 21 and 22 of the seat section 11.v This causes an alignment of holes 33, 89 and 90 on the one rear corner and the alignment of holes 34, 94 and 95 on the other rear corner. Holes 103 and 104 are provided in the forward l ends of the bottom frame members 50 and 53 of the arms and 14 respectively. These holes 103 and 104 become aligned respectively with the hole 32 in the flange 21 and hole 31in the flange 22 of the seat section 11 when the back and arm portion is placed over the seat section. Nut means 1195 and 1% are placed directly overthe holes 103 and 104 respectively and are preferably affixed to'the bottom plate members 50 and 53 in somewhat the same manher as the nut means 91 and 95 are fastened to the bottom plate 35 of the back section 12. The legs 15, '16, 17 and 18 are each provided with floor engaging conical portions such as that shown at 107. At the. top of the lcg15 there is provided an upwardly extending threaded stud 188 formed or fastened integrally therewith. Thus when the leg '15 with its threaded stud 108 passes upwardly through the aligned openings 31 and 104 and rotated causing it to threadedly engage the nut means 106, the leg, seat and arm are rigidly fastened together. Similarly the leg 16 has threaded stud 1 10 passing through the vertically aligned openings 33, 89 and 9t and thereafter threadedly engaging the nut means 91. Finally'the leg 18 as best shown in 'FIGURE'Q has a threaded stud 111 passing upwardly through the vertically aligned openings '34, 94 and 95 preliminary to its threaded engagement with the nut means 96. Thus the attachment of the legs causes the unitary and simple assembly of the several furniture sections into a rigid chair or sofa device. v

There-is thus provided an easy method of constructing furniture by preliminarily making frames for each sec tion of the entire unit, preliminarily upholstering each section, fastening the back and the spaced apart arms rigidly together, placing the preliminarily assembled back a of the seat section 11 upon assembly of'the chair.

6 and arm sections on the seat sections and utilizing the plurality of legs as interlocking means for the several sections. It is immaterial whether the fastening means comprise threads on the legs and complementary, nut

-means on the arm and back sections as: the fastening means could be reversed or take other forms. Following the assembly of the furniture piece by using the legs to interlock the several sections the arm covers or caps 62 and 76 are slid rearwardly onto the cooperative tracks on the top of the frames for the arms 13 and 14. With this construction the application of the upholstery has been relatively simple and yet the completely assembled chair or sofa appears completely finished with all of the stapling of fabric coverings concealed beneath and inside of parts of the various sections. The only remaining openings on the furniture construction are the openings of the back section at one side between the front and rear posts 38 and and at the other side between the front and rear posts 37 and 39. These openings are covered by panels 112 constituting preferably a wooden plate number 113 preliminarily covered with the upholstery fabric 114-and thence fastened with finishing tacks 115 to the perimeter of the'back section openings. p

It should be understood that the outside bottoms of the arms and the rear bottom ofthe back could be equipped with downwardly extending lips adapted to overhang the side and rear edges of the bottom plate 20 The lips or downwardly extending outer flanges would be preferably covered with the upholstery fabric in the same chair or other article of furniture requiring a seat, spaced arms, a back and legs are made in sections with Wooden frames of a simple geometric shape permitting easy covering thereof with upholstery material and subsequently preliminarily assembling the back section and the spaced apart arm sections so that this subassembly may be placed directly onto side flanges of the seat section thus enabling interlocking of the sever-a1 sections by the fastening of the legs through and to various sections. Following the assembly of these units the tops of the arm sections are slid onto the arms-over the tracks and the back section has its side openings closed by the panels 112 as shown in FIGURE 1. The tops of the arms are made removable only because that is the portion of the chair or sofa that wears most readily. This of course enables easy removing of the caps 6 2and 76 for reupholstering or cleaning of soiled fabrics. I
